Abstract : For nano satellite , CCD is difficult to reach the requirements of volume , weight and power consumption in the fields of on2satellite image acquisition such as remote sensing and attitude determination1 CMOS image sensor , with the corre2 sponding characters , provides the potential realization of the image function in nano2sate1 The theory and architectures of CMOS image sensor are introduced , as well as the developing status of it1 The feasibility of its application in the space technology is an2 alyzed , based on the comparison of character of CMOS APS with that of CCD1 All these analysis and studies allow the conclu2 sion that as the CMOS technology and its application technology develop , CMOS image sensor must be a potential replacement of CCD in the field of micro &nano satellite1
Key words : CMOS image sensor ; CMOS APS; miniature camera for remote sensing ; sun sensor ; star tracker
